sequencial cd4017

hi!

could anybody help me on a diagram bout a sequential output of 20 or more??

clock input is 1 Hz, the problem is I can make a maximum of 10 sequencial outputs only(using CD4017).. can CD4017 be cascaded for more outputs???

like after the 10th output, it would pass to the 2nd CD4017s 1st output and the 1st CD4017s 10th output would extinguish?? im really having a hard time doing that.... trying to get rid of the 10th output.. so that it would carry on to the 2nd CD4017...

i would need about 30 sequential outputs...

any help/suggestions welcome :)
